Answer 1

Ответ: 5

Решение:

x + 45 = 10x

x - 10x = -45

-9x = -45

9x = 45

x = 45 / 9

x = 5

Answer 2

Problem Analysis

We are given that a number was increased by 45, resulting in a number that is ten times greater than the original number. We need to find the original number.

Solution

Let's assume the original number is x. According to the problem statement, the number was increased by 45, resulting in a number that is ten times greater than the original number. We can write this as an equation:

x + 45 = 10x

To solve this equation, we can subtract x from both sides:

45 = 9x

Now, we can divide both sides by 9 to solve for x:

x = 45 / 9 = 5

Therefore, the original number is 5.

Answer

The original number is 5.
